OVH Sustained CPU Endurance RunVPS SSD 1 - Nov 09 2018

The sustained CPU endurance test runs a cpu intensive task in a loop for 24 hours.
As maxing out the cpu might be considered abusive, the tests aims to use no more
than 50% of each cpu core on the VPS.

The purpose of this type of test is

first to evaluate the speed to the VPS,

second to evaluate the stability over time of the cpu available to the VPS

and third to detect VPS where the CPU is throttled and
the performance goes down over time after cpu utilization goes over
a threshold the provider considers excessive for a particular plan.

The performance is measured at regular intervals in terms of tasks executed per hour, amount of idle cpu and
amount of "cpu steal".

Overall CPU that the endurance test tries to use across all CPU cores on the VM.

50%

Average iterations per hour

Average number of tasks executed per hour. It represents how much work the VPS was able to achieve per hour. Higher numbers are better.

1331

Coefficient of variation iterations per hour

This represents the dispersion of the number of tasks per hour. It's the standard
variation divided by the mean number of tasks per hour.
It's an indicator on stability of the performance of the VPS. A low standard deviation means
the VPS speed stayed close to constant. A high standard deviation means performance varied
significantly during the test.

8.4%

Average cpu idle

Average percentage of cpu that was idle during the test.
This number should be close to (100 - the target cpu usage (50%)) unless cpu is being throttled.
